Halakhah su Deuteronomio 14:3

Dietary proscriptions include categories of food which are forbidden by their nature and others which are forbidden because of their mode of preparation. Various species of animals, fowl, fish, and creeping things are described in the Torah and declared "unclean" (Lev. 11:1–23 and 41–47, Deut. 14:3–19).

And yet its warning – meaning to say, the explicit negative commandment, besides the punishment that is mentioned here – is from that which is written in the inauguration [of the tabernacle], "it shall not be eaten, as it is holy" (Exodus 29:34). And they, may their memory be blessed, said (Pesachim 24a) that this verse includes in its warning all that which has been spoiled of the [sacrifices] and is not fitting to eat, like notar and piggul. And likewise did they, may their memory be blessed, say (Avodah Zarah 66a) that they are included in the warnings, "You shall not eat any abomination" (Deuteronomy 14:3) – which they expounded (Chullin 114b), "Anything that is abominable for me, is forbidden to eat." And since this is so, we shall say that [that warning (negative commandment) is to make one liable for] additional negative commandments; and the verse here is speaking about the punishment of the one who eats it, as so did the explanation come about it. And that which it stated (Leviticus 7:18), "If it shall surely be eaten on the third day," is meaning to say that he thought about it to eat it on the third day. As so did they, may their memory be blessed, expound (Zevachim 29a), "'And if it shall surely be eaten, etc.' – that is piggul." Bend your ear to hear that the verse is speaking about one who thinks to eat his sacrifice on the third day, that it is spoiled with this thought. And one who eats it is liable for excision, as it is stated about it, "and the soul that eats from it will carry his iniquity." And it is stated about notar (Leviticus 19:8), "And the one who eats it will carry his iniquity, as he has profaned the holy of the Lord, and he shall be excised." And we learned [about] it in Keritot 5a, "Let not an inferential comparison (gezara shava) be light in your eyes; as behold piggul is one of the [important] bodies of Torah, and Scripture only taught it through a gezara shava." As we learn it] from notar, from [the use of] ‘iniquity’ [in both cases] – "just like there it is excision, here too it is excision."

To not eat of the swarming creatures of the waters: To not eat of the swarming creatures of the waters, as it is stated (Leviticus 11:43), "You shall not abominate your souls with any swarming creature that swarms, and you shall not defile yourselves with them and become impure through them." And the substance of a swarming creature of the waters is well-known; that it is from the minute creatures that swim in the water - and they are called the swarming creatures of the waters. And this negative commandment is specific to them, [and] besides the negative commandment that is specific to the impure fish; as these are not included as fish at all, since they are a completely different species of its own. That is the opinion of Rambam, may his memory be blessed, (Sefer HaMitzvot LaRambam, Mitzvot Lo Taase 179), about this verse, that it comes to teach about this. But Ramban, may this memory be blessed, (on Sefer HaMitzvot, Root 9, s.v. veraiti lerav z"l) disagrees with him on this and wrote, that this negative commandment is not a specific negative commandment about any swarming creature; but rather that it is from the general negative commandments for which we do not administer lashes, like "You shall not eat any abomination" in Deuteronomy 14:3 at the beginning of the sections of the prohibited animals. And so [too,] here at the end of all of them, it stated, "You shall not abominate your souls" with all of the walkers of the ground that I have prohibited. And grouped in this was the prohibition of the impure beast, the prohibition of the impure fowl, the flying swarming creature and the swarming creature of the ground. As all the forbidden and the distanced is included in abomination, as [with] "For He did not disparage nor abominate the plea of the lowly" (Psalms 22:25). And both of them, may their memories be blessed, wrote at length about this negative commandment and involved in it that which [the Sages], may their memory be blessed, said in the Gemara [in] Makkot 16b, "If he ate a putita, he is lashed four [sets], an ant five, a wasp six." And each one explains what appears [correct to him] about the matter.
